Kernrechtsfrage
Whether the federal complaint could be entered into despite non-payment of the cost advance within the non-extendable deadline.
Extrahierter Entscheid
No. The complaint had to be declared inadmissible because the advance was neither paid in cash nor duly evidenced as paid by bank/postal debit within the deadline.
Extrahierte Begründung
After a formal warning under Art. 62(3) BGG, the appellant did not comply with the advance-payment order. Under Art. 108(1)(a) BGG, the court therefore issued a non-entry decision.
